[A woman with a growing mass near the anus]. / Een vrouw met een groeiende massa tussen de billen.

A 58-year-old woman visited the surgical outpatient clinic because of a mass near the anus that had existed for years and had now grown to a size that made sitting impossible. With histological examination of the 6 x 10 cm exofytic, condylomatic mass, the diagnosis 'giant condyloma acuminatum' was made. Radical excision was performed, the patient recovered well.
